Problems solved by technology
[0003] At present, the main problems affecting perovskite solar cells are their packaging and process stability.
Perovskite materials with different components will undergo phase change under high temperature conditions, which determines that perovskite components need to be packaged at low temperature. The existing photovoltaic packaging mode no longer uses perovskite component packaging.
[0004] At the same time, the traditional metal layer is in contact with the perovskite light-absorbing layer, causing metal ions to enter the perovskite material to react, changing the properties of the perovskite material and reducing its stability.
